WebP v0.5.3 build 2026-04-06 beta

[pixelsearch]

Quick test after download 5 min ago : new version (x86) works fine for showing progress in Console & aborting (Esc) during progress, in Example 9. Well done !

Updated to WebP v0.3.6 build 2025-07-02 beta -> you can convert now GIF animated files to WebP animated files (see Example10.au3 on my 1Drv).

[pixelsearch]

Impressive, an animated gif file (8-cell.gif : 3554 KB) became (ConvertedFromGIF.webp : 394 KB) this is about 9 times smaller with good quality. Console output :

GIF filesize:  3638957
WebP filesize: 403202

Well done UEZ

[UEZ]

In the example I've chosen 10 (out of 100 = nearly no compression). You may see artifacts in the WebP file with 10 as quality.

Btw, I don't know why but the WebP animation is one frame less at least for one gif. Maybe depends on the gif file...

 

Anyhow, thanks for testing. 👍

You're welcome, it's the least we can do for you

Just curious : example 8 creates a WebP animation from 4 possible types of image files :

"images (*.jpg;*.png;*.bmp;*.gif)"

Do you think it would be possible to add this 5th type of image file, if not too complicated ?

"images (*.jpg;*.png;*.bmp;*.gif;*.webp)"

Thanks

[UEZ]

Updated to WebP v0.3.7 build 2025-07-03 beta

You can now create WebP anim files from WebP image files and you can extract frames from a WebP anim file to WebP image file format.

Supported GDIPlus image formats: "bmp", "gif", "jpg", "tif", "png"

[pixelsearch]

@UEZ hello. I got 2 questions if you don't mind :

1) Func WebP_CreateWebPCreateAnim
As $aFilenames must be 2D, could the following line in the function use a simpler syntax ?

; $tArrayFramesDelay.delay($i + 1) = UBound($aFilenames, 2) ? ($aFilenames[$i][1] > 0 ? $aFilenames[$i][1] : $iDefaultDelay) : $iDefaultDelay

$tArrayFramesDelay.delay($i + 1) = $aFilenames[$i][1] > 0 ? $aFilenames[$i][1] : $iDefaultDelay

2) Concerning this line in example 8 :

$aFrames[$i - 2][1] = $iGDelay + $i * 2

Could you please explain the need of "$i * 2" which will slowly increase the delay between each frame ?

For example, using the 10 "crow" pics to create a WebP animation, here are the delays in the structure :

64 ms after frame 1  (60 + 2*2)
82 ms after frame 10 (60 + 11*2)

If not mistaken, when an animation got 50 frames, it would add 100ms during the last frames, 200ms if 100 frames etc...

Thanks

The idea was check if array is 2D but you are right, instead of checking permanently the array, one check should be enough -> fixed.

I wanted to see if delays are properly added to the animation. There no other reason to slow down the frames. 🙂

The idea was check if array is 2D

 So my secret guess was wrong on this 1st point
I thought that maybe, while scripting it, you'd allow a 1D array to be used too, containing only the filenames, something like this in example 8 alt :

;~ Global $aFrames[UBound($aFiles) - 2][2]
;~ For $i = 2 To UBound($aFiles) - 1
;~     $aFrames[$i - 2][0] = $aFiles[1] & "\" & $aFiles[$i]
;~     $aFrames[$i - 2][1] = $iGDelay + $i * 2
;~ Next

Global $aFrames[UBound($aFiles) - 2]
For $i = 2 To UBound($aFiles) - 1
    $aFrames[$i - 2] = $aFiles[1] & "\" & $aFiles[$i]
Next

Of course it requires to alter/duplicate a couple of lines in Func WebP_CreateWebPCreateAnim, to take care of the possibility that the array may be 1D

In this case, your original line shows it power again, accepting that the array is 1D or 2D :

$tArrayFramesDelay.delay($i + 1) = UBound($aFilenames, 2) ? ($aFilenames[$i][1] > 0 ? $aFilenames[$i][1] : $iDefaultDelay) : $iDefaultDelay

Just for fun, I tested this yesterday (1D array in example 8 and in Func WebP_CreateWebPCreateAnim), everything worked nicely and the default delay of 75ms between frames was applied.

Yesss, my secret guess was right on this second point

For the record, here is how an old version of Animation Shop (bundled with PaintShop Pro) handles the delays while creating an animated gif :

We just indicated a global delay applied between all frames (10/100th seconds in the pic, that's 100ms) . This correspond to your $iDefaultDelay = 75 in the function.

When the animation is done, there's a possibility to alter one/several/all delays : for example I changed the delay of frame 2 to 150ms in the pic above (see "Frame;2 Delay:15") . Applied to your function, this corresponds to the delays the user may indicate in the 2D array (last column)

So that's a good reason for using a 2D array. You can alter some important delays when needed. Try to do it with a 1D array !

Thanks for all your work and have a great evening

Yes, that was the reason for that line if Array is only 1D. 

 

When you display the animation, you can choose to play it one time, n times or endless but there is also an option to set loop_count. I will add it as an parameter that external players can play it accordingly.

Thanks for your feedback!

[UEZ]

Updated to v0.3.8 build 2025-07-04 beta

• added loop count parameter for the 3 animation functions. Default = 0 which is endless.
• added WebP_GetImagesDiffFromFile() which can compare two WebP files which same dimension

Hellooo

Just to let you know : example 11 throws an error with the 4th parameter found in the actual script (as it corresponds to your config)

Global $aResult = WebP_GetImagesDiffFromFile($aFiles[0] & "\" & $aFiles[1], $aFiles[0] & "\" & $aFiles[2], 2, "c:\_BZ25LN\Coding\FreeBASIC\__UEZ\_Graphical Stuff\WebP\WebP-dll.dll")

Of course it works fine without the 4th parameter :

Global $aResult = WebP_GetImagesDiffFromFile($aFiles[0] & "\" & $aFiles[1], $aFiles[0] & "\" & $aFiles[2], 2)

[UEZ]

Oops, forgot to remove the manual path to the DLL. 

Fixed.

@UEZ Hi. Two points to share with you :

1) Example 8
* If the output animation "TestAnim.webp" already exists, then no error is thrown if the user selects only 1 file for the animation (what a silly idea !) and the old animation "TestAnim.webp" is displayed (bad behavior)

* If the output animation "TestAnim.webp" doesn't exist, then an error is thrown if the user selects only 1 file for the animation (this should be the standard behavior, no matter the animation already exists or not)

A possible solution could be to delete in all cases the old animation that may exist, before processing.

2) Example 8 with function _ShowParams()

Could you please try this modified version of Example 8 and give your opinion ?
It allows to modify through a GUI any optional parameter from Func WebP_CreateWebPCreateAnim
This could be useful when functions got plenty of parameters (20 in this case) . Also the function could be easily adaptable to other scripts, as it is self contained
Thanks

Update July 6th, 2025

Gui design (minor)
Insensitive flag in one RegEx pattern
Return value , @error , @extended : all checkable in main
Each parameter got its explanative tooltip (as found in UEZ's UDF)

Update July 7th, 2025

* $GUI_EVENT_CLOSE reacts now like the button "Cancel" : it exits the script.
This is the behaviour UEZ adopted in his example "101" found on his onedrive link (see 1st post for the link) . I'm glad you could simply copy/paste the function _ShowParams() from one script to the other and everything worked smoothly 

* Also, based on example "101", I replaced this line...

$sFuncExec &= GUICtrlRead($idPar[$i]) & ($i < UBound($aArray) - 1 ? "," : ")")

...with

$sFuncExec &= StringStripWS(GUICtrlRead($idPar[$i]), 3) & ($i < UBound($aArray) - 1 ? ", " : ")")

It's safer as it strips possible spaces left by the user in the Input fields.
A difference with example "101" : I added a space after the comma which means ", " instead of ","
It allows to construct the variable $sFuncExec with parameters nicely separated, visible in the Console during debug process (or always if the line ConsoleWrite($sFuncExec & @CRLF) is left uncommented in the script) :

WebP_CreateWebPCreateAnim($Par1, $Par2, 75.0, 0, 4, 60, 50, 1, 6, 0, 100, 1, 1, 100, 0, 0, $WEBP_PRESET_DEFAULT, 75, 0, "")

Update August 4th, 2025

Modified the line which checks the dll version, to reflect UEZ last update (note : this will be updated again to indicate "0.4.4" in a few days)

If WebP_Ver2() < "0.4.3" Then Exit MsgBox($MB_ICONERROR, "ERROR", "DLL Version v0.4.3.+ required!", 30)

Update August 19th, 2025

@UEZ Added a help button, to display in a separate GUI all the parameters and their meanings. Tooltips are still here of course, but sometimes we need to have a look at several parameters meaning at same time : it happened to me yesterday while converting an animated GIF to mp4 (using ffmpeg) then the same animated GIF to an animated WebP, using your example 10.1

Hi @pixelsearch

thank again for your feedback. 

Regarding

1) my bad. The example 08 doesn't contain a check if creation fails - it just proceeds. Easy to fix:

Global $sFile = @ScriptDir & "\TestAnim.webp"
Global $iResult = WebP_CreateWebPCreateAnim($aFrames, $sFile)
If $iResult < 1 Or @error Then
    ConsoleWrite($iResult & " / " & @error & @CRLF)
    _GDIPlus_Shutdown()
    Exit MsgBox($MB_ICONERROR, "Error", "Something went wrong creating the animation!")
EndIf

2) to be honest - I'm too lazy to create a GUI with all parameters.  I'm not sure if all the parameters are required or will ever be needed, but I'm happy to include this as Example08.1.au3. It would only make sense if the value range per parameter was listed in the GUI. The ranges should be described in the UDF header.

 

Edited July 5, 2025 by UEZ

[pixelsearch]

Glad you liked it
imho _ShowParams() is great because we don't need to check any Default value in the UDF to use it.

For example, if I want to use $iDefaultDelay (the 18th parameter) with a value of 150, I don't need to indicate any of the 15 preceding optional values in the calling script.

Another solution could have been to add 18 lines in the UDF but that's very boring :

If ... = Default Then ...
If ... = Default Then ...

And then call the function with endless Default parameters until the 18th parameter is reached, very boring too !

Also, it seems that the function could be easily reusable in any script : only the number of mandatory parameters should change, for example, with 3 mandatory parameters :

Func _ShowParams($sFuncName, ByRef $Par1, ByRef $Par2, ByRef $Par3)

But well, I just quickly scripted it, there will be probably things to modify in it, we'll see...

To achieve this, I just tried the following pattern, it looks promising :

The string "WebP_CreateWebPCreateAnim" will be replaced by $sFuncName in the final version, to make it portable. Return in array[0] is :

;                  $level               - [optional] an unknown value. Default is 6. Between 0 (fastest, lowest compression) and 9 (slower, best compression) only valid for lossless = 1!

;                  $WebPPreset          - [optional] an unknown value. Default is $WEBP_PRESET_DEFAULT.
;                  $iDefaultDelay       - [optional] an integer value. Default is 75. Delay in milli seconds.
;                  $pCallback           - [optional] a pointer value. Default is 0. Pointer to a callback address for progress hook.
;                  $sPath2DLL           - [optional] a string value. Default is "". Path to WebP dll if not in script dir.

After that we'll see if it needs to be splitted into 20 lines (20 tooltips for the 20 labels while creating $hGUIPar)

You may ask : "why the need of the non-capturing group ?

It's just to make the pattern compatible with some UDF's of other users, for example @Melba23 in GUIListViewEx.au3 , function _GUIListViewEx_Init
The same pattern (using $sFuncName etc...) will output this :

(?Usi)_GUIListViewEx_Init\(.*(; Parameters.*)\R; (?:Return value|Requirement).*Func _GUIListViewEx_Init\(

 

; Parameters ....: $hLV       - Handle or ControlID of ListView
;                  $aArray    - Name of array used to fill ListView.  "" for empty ListView
;                  $iStart    - 0 = ListView data starts in [0] element of array (default)
;                               1 = Count in [0] element
;                  $iColour   - RGB colour for insert mark (default = black)
;                  $fImage    - True  = Shadow image of dragged item when dragging
;                               False = No shadow image (default)
;                  $iAdded    - 0       - No added features (default).  To get added features add any of the following values
;                               + 1     - Sortable by clicking on column headers
;                               + 2     - Do not "select all" when editing item text
;                               + 4     - Continue edit within same ListView by triple mouse-click on editable column
;                               + 8     - Headers editable by Ctrl-click (only if column editable)
;                               + 16    - User coloured header
;                               + 32    - User coloured items
;                               + 64    - No external drag
;                               + 128   - No external drop
;                               + 256   - No delete on external drag/drop
;                               + 512   - No internal drag/drop
;                               + 1024  - Single cell highlight (forces single row selection)

This one should be just a bit harder to split into 6 tooltips... but never say never

Edit: @UEZ each time the _ShowParams() function will be updated, I'll do it in the same post above, not polluting your thread with new posts.

For example, I just updated it now :

Gui design (minor)
Insensitive flag in one RegEx pattern
Return value , @error , @extended : all checkable in main

Next step should be to add the tooltips as discussed above (note: it has been done this evening)
Thanks for reading and have a great sunday !

Updated to WebP v0.4.1 build 2025-07-10 beta.

You can now play WebP animation in a separated thread. See WebP Example14 .1.au3 and WebP Example15.au3

Running it as is, I get the following error: "Couldn't find WorkerW under Progman." I then replaced your _WinAPI_FindWindowEx() function with asnippet from this piece of code from @argumentum, and it worked fine:

Func __WinAPI_FindWindowEx()
    Local $hWorkerW = 0, $hProgman = _WinAPI_GetShellWindow() ; WinGetHandle("[CLASS:Progman]")
;~  _SendMessage($hProgman, 0x052C) ; <<<<<< force the creation of a WorkerW handle under Progman

    ; https://stackoverflow.com/questions/34952967/drawing-to-the-desktop-via-injection
    ; https://github.com/rocksdanister/lively/issues/2074
    ; _WinAPI_SendMessageTimeout($hProgman, 0x052C, 0, 0, 3000, $SMTO_NORMAL) ; same as _SendMessage()

    If Not $hWorkerW Then ; dah
        Local $aEnumWindows = _WinAPI_EnumWindows(False)
        For $n = 1 To UBound($aEnumWindows) - 1
            If $aEnumWindows[$n][1] <> "WorkerW" Then ContinueLoop
            If _WinAPI_GetParent($aEnumWindows[$n][0]) = $hProgman Then
                $hWorkerW = $aEnumWindows[$n][0]
                ExitLoop ; but is likely one at the end of the Z-order
            EndIf
        Next
    EndIf

    ; ConsoleWrite("WorkerW = " & $hWorkerW & @CRLF)
    If Not $hWorkerW Then $hWorkerW = $hProgman
    Return $hWorkerW
EndFunc   ;==>__WinAPI_FindWindowEx

By the way, very great effect! 👍

@Giannithanks for your feedback. I changed the code for example 14 / 14.1 if @argumentum's functions works better for all OS'.

Btw, I missed to dispose the animation and the old DLL will cause a memory leak. The new version should be working properly!
